What is Irlen Syndrome?
Irlen Syndrome is a light-based visual processing problem. Specifically, it is a cluster of symptoms caused when the brain struggles to process light and visual stimuli efficiently. Irlen Syndrome is not a reading problem, is not dyslexia, is not an issue with sight or vision, even though it can affect what some people see and can make reading and other visual activities more difficult. Irlen Syndrome is an information and sensory processing problem.
When someone has Irlen Syndrome, their brain overreacts to light and visual stimuli. This over-activity and inability to effectively process visual stimuli creates a variety of visual, physical, cognitive, emotional, and neurological symptoms. Light sensitivity is very common with Irlen Syndrome. Irlen Syndrome is hereditary and tends to run in families, affecting males and females equally. However, an individual can also acquire symptoms of Irlen Syndrome as a result of illness, medical procedures, or traumatic brain injury (or concussion).
This problem can manifest itself differently for each individual. This problem is not remediable and is often a lifetime barrier to learning and performance. If you suffer from any of the following, Irlen Syndrome might be your problem:
- Print looks different
- Environment looks different
- Slow or inefficient reading
- Poor comprehension
- Eye strain
- Fatigue
- Headaches
- Difficulty with math computation
- Difficulty copying
- Difficulty reading music
- Poor sports performance
- Poor depth-perception
- Low motivation
- Low self-esteem
